They can range in size from just a few inches tall to more than 12 feet in the case of the tree ferns. Some types of ferns are tropical. Others quite hardy. Their versatility aside, ferns are valuable in the home and garden because they prefer shade. In the landscape, ferns bring fresh green life to those hard-to-design dim corners.
Prokaryotic cells have various shapes; the four basic shapes are: Cocci - spherical Bacilli - rod shaped Spirochaete - spiral shaped Vibrio - comma shaped.
THE PROKARYOTIC CELL: BACTERIA. 1. There are three basic shapes of bacteria: coccus, bacillus, and spiral. 2. Based on planes of division, the coccus shape can appear in several distinct arrangements: diplococcus, streptococcus, tetrad, sarcina, and staphylococcus.or example, bacillus-shaped bacteria that have an inactivated MreB gene become coccoid shaped, and coccus-shaped bacteria naturally lack the MreB gene. Most bacteria come in one of three basic shapes: coccus, rod or bacillus, and spiral.
